FHWA Modifies Special Experimental Highway Project Applications

## Summary

The Federal Highway Administration is changing how people apply for three special projects (SEP-16, SEP-15, and TE-045) to make the process simpler and faster. This update affects anyone applying to these projects and aims to save time and effort without changing funding. Comments on the new process are open until October 26, 2026, so get your thoughts in soon!

## Abstract

FHWA is seeking comments on a new process for submission and evaluation of applications under SEP-16, SEP-15, and TE-045 (collectively the "three experimental projects"). The purpose of the modification is to achieve a streamlined, uniform process to reduce burden and improve the efficiency of the application and evaluation process for all three experimental projects.
